Template Validation supports any properties locally available in the global _data managed by the super admin user. The _data property names that match a partially entered template name will be offered in the dropdown of matches. Any _data used on the URL at runtime is not supported (and will not validate) with this functionality because it is not known at design time, only runtime. A global _data property used in a template in a form/flow that is downloaded and uploaded into another frevvo instance that does not have that _data property will be flagged as an invalid template. In this situation, the designer can either ignore the error, update the default _data properties or, if the validation is for a flow/form or flow step property that prevents saving the properties, add a hidden control of the same name so that validation passes.

Setting Global Data in the Configuration



Properties listed in the  the can be overridden with properties prefixed by frevvo._data.<property name> in the following configuration files in the file located in <frevvohome>\tomcat\conf. Note the syntax for the properties has a dot before and after the _data.

  • If you are using the frevvo tomcat bundle, you can add the frevvo._data properties in the:
    • - this file is typically created by the System Administrator to override parameters in a container web.xml file.

This approach is helpful when deploying multiple environments. Let's say your organization has a Development, Production and UAT environment for

.  All three have the frevvo DB Connector configured for that environment. If you make a copy of the Production environment and database to create your UAT environment, you would have to download the _data properties file, make the changes to point to the DB Connector in the UAT environment, then upload the file again.

It is easier to create property files with a frevvo._data.dbURL parameter pointing to the correct locations for each environment.

This parameter in the frevvo.xml file would look like this:

Code Block
<Parameter name="frevvo._data.dbURL" value="http://<server>:<port>/database/listManagers" override="false" />

The same parameter in the web.xml file would look like this:




The same parameter in the file would look like this:


As mentioned above, you can write the URL using a template such as {dbURLl}/database/listManagers. Then define the variable dbURL for the development, UAT and Production environments in the properties file you are using..
